Called just before EF intends to call CreateCommand().

public virtual Microsoft.EntityFrameworkCore.Diagnostics.InterceptionResult<System.Data.Common.DbCommand> CommandCreating (Microsoft.EntityFrameworkCore.Diagnostics.CommandCorrelatedEventData eventData, Microsoft.EntityFrameworkCore.Diagnostics.InterceptionResult<System.Data.Common.DbCommand> result);

abstract member CommandCreating : Microsoft.EntityFrameworkCore.Diagnostics.CommandCorrelatedEventData * Microsoft.EntityFrameworkCore.Diagnostics.InterceptionResult<System.Data.Common.DbCommand> -> Microsoft.EntityFrameworkCore.Diagnostics.InterceptionResult<System.Data.Common.DbCommand>
override this.CommandCreating : Microsoft.EntityFrameworkCore.Diagnostics.CommandCorrelatedEventData * Microsoft.EntityFrameworkCore.Diagnostics.InterceptionResult<System.Data.Common.DbCommand> -> Microsoft.EntityFrameworkCore.Diagnostics.InterceptionResult<System.Data.Common.DbCommand>

Public Overridable Function CommandCreating (eventData As CommandCorrelatedEventData, result As InterceptionResult(Of DbCommand)) As InterceptionResult(Of DbCommand)

Parameters

eventData: CommandCorrelatedEventData

Contextual information about the command and execution.

result: InterceptionResult<DbCommand>

Represents the current result if one exists. This value will have HasResult set to true if some previous interceptor suppressed execution by calling SuppressWithResult(TResult). This value is typically used as the return value for the implementation of this method.

Returns

InterceptionResult<DbCommand>

If HasResult is false, the EF will continue as normal. If HasResult is true, then EF will suppress the operation it was about to perform and use Result instead. A normal implementation of this method for any interceptor that is not attempting to change the result is to return the result value passed in.

Implements

CommandCreating(CommandCorrelatedEventData, InterceptionResult<DbCommand>)
